Russian Reactions to Reagan's ‘Maritime Strategy’

The US Navy's audacious Maritime Strategy of the 1980s is often credited with acting as a key catalyst to the demise of the USSR. In assessing the role of strategic missile submarine “bastions” in the country's overall military strategy, the authors are skeptical of the above thesis, explaining that Moscow actually viewed deployments of Tomahawk land-attack cruise missiles on to US submarines (versus direct threats against the Soviet Navy itself) as the most alarming threat. The authors concede that the arms race played a role in the collapse of the USSR, but deny a direct connection with Soviet naval development citing the relatively minor naval proportion of overall defense spending. For the difficulties facing the fleet at the end of the Cold War, they instead blame deep systemic problems internal to the Soviet Navy.

Maintenance scheduling for modular systems: Modeling and algorithms

We study new models of scheduled maintenance management for modular systems, consisting of multiple components with respective cycle limits. The cycle limit of each component specifies the time interval in which this component must be repaired or replaced. The goal is to compute a feasible maintenance schedule that minimizes the cost associated with component maintenance. Applications of these models arise in Air Force aircraft maintenance as well as in other arenas with required preventive maintenance. The typical cost structures that arise in practical settings are submodular, which make the resulting models computationally challenging. We develop two efficient and operationally tenable approximation algorithms. We prove constant factor worst‐case guarantees for both algorithms, and present computational experiments showing that these algorithms perform within a few percent of optimality on operationally relevant instances. © 2014 Wiley Periodicals, Inc.

弹药不足条件下小口径舰炮射击方法

在未来的海战中,小口径舰炮可能要多次抗击来袭的空中目标.在最后一次抗击中,很可能会出现剩余弹药不再满足整个射击航路段所需的弹药数这种情况.此时如何合理地确定射击方法将对小口径舰炮武器系统的射击效果产生直接的影响.在现有战术软件的基础上,提出压缩开火距离数学模型,可以明显提高小口径舰炮武器系统,对空中目标尤其是导弹目标的命中概率.
